Resumo Objetivou-se realizar uma análise espacial da taxa de mortalidade hospitalar (TMH) por síndrome respiratória aguda grave (SRAG) atribuída à COVID-19 em crianças e adolescentes no Brasil no período de 2020 a 2021. Utilizou-se o método de cluster para agrupar as unidades federativas (UFs) com base na TMH. Em 2020, clusters com altas TMHs foram formados por UFs Norte/Nordeste. Em 2021, houve redução na TMH. Os clusters com maiores taxas permaneceram na região N/NE. Diferenças regionais foram observadas nas TMHs. Os achados podem refletir as desigualdades sociais e o acesso à atenção hospitalar, principalmente na faixa etária de menores de 1 ano pela gravidade da doença neste grupo.

Abstract The objective was to perform a spatial analysis of the hospital mortality rate (HMR) due to severe acute respiratory syndrome (SARS) attributed to COVID-19 among children and adolescents in Brazil from 2020 to 2021. A cluster method was used to group federal units (FUs) based on HMR. In 2020, clusters with high HMRs were formed by north/northeast FUs. In 2021, there was a reduction in HMR. Clusters with higher rates remained in the N/NE region. Regional differences were observed in the HMR. The findings may reflect social inequalities and access to hospital care, especially in the under 1-year-old age group due to the severity of the disease in this group.

Abstract Objective To compare the patterns of systemic inflammatory response in women with epithelial ovarian cancer (EOC) or no evidence of malignant disease, as well as to evaluate the profile of systemic inflammatory responses in type-1 and type-2 tumors. This is a non-invasive and indirect way to assess both tumor activity and the role of the inflammatory pattern during pro- and antitumor responses. Materials and Methods We performed a prospective evaluation of 56 patients: 30 women without evidence of malignant disease and 26 women with EOC. The plasma quantification of cytokines, chemokines, and microparticles (MPs) was performed using flow cytometry. Results Plasma levels of proinflammatory cytokines interleukin-12 (IL12), interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α) interleukin-1 beta (IL-1β), and interleukin-10 (IL-10), and C-X-C motif chemokine ligand 9 (CXCL-9) and C-X-C motif chemokine ligand 10 (CXCL-10) were significantly higher in patients with EOC than in those in the control group. Plasma levels of cytokine interleukin-17A (IL-17A) and MPs derived from endothelial cells were lower in patients with EOC than in the control group. The frequency of leukocytes and MPs derived from endothelial cells was higher in type-2 tumors than in those without malignancy. We observed an expressive number of inflammatory/regulatory cytokines and chemokines in the cases of EOC, as well as negative and positive correlations involving them, which leads to a higher complexity of these networks. Conclusion The present study showed that, through the development of networks consisting of cytokines, chemokines, and MPs, there is a greater systemic inflammatory response in patients with EOC and a more complex correlation of these biomarkers in type-2 tumors.

Resumo Objetivo Comparar os padrões de resposta inflamatória sistêmica em mulheres com câncer epitelial de ovário (CEO) ou sem evidência de doença maligna, bem como avaliar o perfil de respostas inflamatórias sistêmicas em tumores dos tipos 1 e 2. Esta é uma forma não invasiva e indireta de avaliar tanto a atividade tumoral quanto o papel do padrão inflamatório durante as respostas pró- e antitumorais. Métodos Ao todo, 56 pacientes foram avaliados prospectivamente: 30 mulheres sem evidência de doença maligna e 26 mulheres com CEO. A quantificação plasmática de citocinas, quimiocinas e micropartículas (MPs) foi realizada por citometria de fluxo. Resultados Os níveis plasmáticos das citocinas pró-inflamatórias interleucina-12 (IL12), interleucina-6 (IL-6), fator de necrose tumoral alfa (tumor necrosis factor alpha, TNF-α, em inglês), interleucina-1 beta (IL-1β), e interleucina-10 (IL-10), e da quimiocina de motivo C-X-C 9 (CXCL-9) e da quimiocina de motivo C-X-C 10 (CXCL-10) foram significativamente maiores em pacientes com EOC do que nos controles. Os níveis plasmáticos da citocina interleucina-17A (IL17A) e MPs derivados de células endoteliais foram menores em pacientes com CEO do que no grupo de controle. A frequência de leucócitos e de MPs derivadas de células endoteliais foi maior nos tumores de tipo 2 do que naqueles sem malignidade. Observou-se um número expressivo de citocinas e quimiocinas inflamatórias/regulatórias nos casos de CEO, além de correlações negativas e positivas entre elas, o que leva a uma maior complexidade dessas redes. Conclusão Este estudo mostrou que, por meio da construção de redes compostas por citocinas, quimiocinas e MPs, há maior resposta inflamatória sistêmica em pacientes com CEO e correlação mais complexa desses biomarcadores em tumores de tipo 2.

ABSTRACT Objective: To compare the agreement of images in white light (WL), fluorescence (FL), and digital radiographs (DR), on the diagnosis and treatment decisions for occlusal caries lesions against a micro-CT gold standard. Material and Methods: Ten extracted third molars, with enamel and/or dentin caries (ICDAS 2-4), were included. Occlusal surface images were acquired with an intraoral camera (SoproLife®) in WL and FL modes. DR was obtained using an intraoral X-ray and a semi-direct digital system. A total of 780 images were needed, organized in a template, to be later examined by twenty-six dentists invited to compose the study. The Generalized Estimation Equations model was used to compare the proportions of the correct answers between the three methods and the gold standard. When significant, Bonferroni post-hoc test was used to identify differences (α=5%). Results: Most of the examiners were specialists (76.9%) with 14.5 years of experience. All diagnostic methods were similar and showed low agreement (DR 12.7%, WL 16.5%, and FL 16.5%) compared with gold standard caries diagnostic scores. Regarding treatment decisions, mean agreement for all diagnostic methods was higher (43.2%; p<0.001), and among all methods, WL (48.1%) and FL (51.2%) modes performed better than DR (30.4%, p<0.001). Conclusion: SoproLife® images could help clinicians to propose rational, minimally invasive treatments for occlusal caries lesions.

ABSTRACT Chagas disease (CD) is a neglected disease caused by the protozoan Trypanosoma cruzi. It has high morbidity and mortality rates and mainly affects socially vulnerable populations. This is a cross-sectional study, with retrospective and prospective data collection. Using questionnaires applied to environmental surveillance coordinators, we characterized the status of CD surveillance activities in municipalities endemic for the disease in Northern Minas Gerais State (MG) and Jequitinhonha Valley (Vale do Jequitinhonha). Moreover, we spatialized the vulnerability index for chronic CD in the study area. The population consisted of 22 environmental surveillance coordinators, active in 2020, from Northern MG and Jequitinhonha Valley, 21 municipalities included in the SaMi-Trop research project, and Montes Claros municipality. After applying the questionnaires to the coordinators, a descriptive analysis of the variables was performed. To characterize the active municipalities, the explanatory variables collected in the questionnaire were compared with the dichotomous variable. Bivariate descriptive analysis was performed. Finally, geoprocessing techniques were used to spatialize the data and prepare maps. Regarding the team of endemic combat agents (ECA), 90.9% reported the lack of a specific team for CD vector control actions. Of the 22 municipalities participating in this study, nine were active (41.1%). Only 25% (n=2) of active municipalities (9% of the municipalities studied) met the target of visiting 50% of households per year. Finally, 81.1% of the coordinators stated that in their municipality, they developed actions linked to primary health care (PHC). The implementation of CD surveillance activities weakened in the endemic region. Few municipalities have a surveillance team, with low regularity of active surveillance and noncompliance with the program’s goal. The results suggest insufficient recording of activities in the information system, considering that there are municipalities that report performing the activities, but no production record was observed in the system.

ABSTRACT Objectives: to analyze the influence of sociodemographic and clinical variables, as well as the surgical checklist adherence score, on the occurrence of surgical site infection among patients undergoing myocardial revascularization. Methods: an observational, longitudinal, retrospective study was conducted at a university hospital, involving 266 medical records of patients who underwent myocardial revascularization surgery. Instruments containing sociodemographic, clinical, and infection-related variables were used, along with the Perioperative Surgical Safety Checklist. Descriptive, bivariate, and logistic regression analyses were employed. Results: surgical site infection occurred in 89 (33.5%) patients. There was a statistically significant association between body temperature outside the range of 36 degrees Celsius to 36.5 degrees Celsius (p=0.01), the presence of invasive devices (p=0.05), surgical procedures with the anticipation of critical events (p<0.001), and the occurrence of infection. Conclusions: body temperature, the presence of invasive devices, and surgical procedures with the anticipation of critical events were significant factors contributing to an increased risk of infection.

Abstract This study aimed to evaluate the contribution of oral and maxillofacial pathology laboratories (OMPLs) in Brazilian public universities to the diagnosis of lip, oral cavity, and oropharyngeal squamous cell carcinoma (SCC). A cross-sectional study was performed using biopsy records from a consortium of sixteen public OMPLs from all regions of Brazil (North, Northeast, Central-West, Southeast, and South). Clinical and demographic data of patients diagnosed with lip, oral cavity, and oropharyngeal SCC between 2010 and 2019 were collected from the patients’ histopathological records. Of the 120,010 oral and maxillofacial biopsies (2010-2019), 6.9% (8,321 cases) were diagnosed as lip (0.8%, 951 cases), oral cavity (4.9%, 5,971 cases), and oropharyngeal (1.2%, 1,399 cases) SCCs. Most cases were from Brazil’s Southeast (64.5%), where six of the OMPLs analyzed are located. The predominant profile of patients with lip and oral cavity SCC was Caucasian men, with a mean age over 60 years, low schooling level, and a previous history of heavy tobacco consumption. In the oropharyngeal group, the majority were non-Caucasian men, with a mean age under 60 years, had a low education level, and were former/current tobacco and alcohol users. According to data from the Brazilian National Cancer Institute, approximately 9.9% of the total lip, oral cavity, and oropharyngeal SCCs reported over the last decade in Brazil may have been diagnosed at the OMPLs included in the current study. Therefore, this data confirms the contribution of public OMPLs with respect to the important diagnostic support they provide to the oral healthcare services extended by the Brazilian Public Health System.

Abstract The survival of endodontically treated teeth depends on the remaining tooth structure. The aim of this study was to evaluate the impact of different access cavities on root canal preparation, restorative protocol, and fracture resistance of endodontically treated teeth. Fifty-six mandibular molars were divided into control (n=8) and experimental (n=16) groups according to access cavity: Traditional, Conservative, and Truss; and redistributed (n=8) according to instrumentation protocols: Reciproc Blue and R-motion. After, teeth were scanned in micro-CT and then filled and redistributed according to composite resin restoration (n=8): Filtek One BulkFill and Filtek Z350. A new micro-CT scan was performed to analyze the restorative material. Then, samples were submitted to fracture resistance testing and the failure pattern was determined. Data were analyzed using paired T-test, ANOVA, Tukey, and chi-square tests (α=0.05). In Truss, R-Motion promoted less transportation in different thirds of root canals. Higher percentages of voids (5.05%) and filling material (11.7%) were observed in Truss. Fracture resistance values were higher for the control group, followed by Truss, Conservative, and Traditional. The predominant failure pattern was type-II. In Truss, reciprocating instruments with smaller taper showed less canal transportation. Also, Truss provided higher values of fracture resistance, although it presented a higher percentage of voids and remaining filling material. Thus, in Truss, reciprocating files with smaller taper showed less canal transportation, and these cavities provided higher values of fracture resistance, although it presented a higher percentage of voids and remaining filling material.

ABSTRACT. Unpaid caregivers of people living with dementia tend to suffer mental health problems as a result of the negative effects associated with the care tasks. Thus, psychosocial interventions for this population group are necessary. iSupport is an online support program for caregivers that was created by the World Health Organization. Objective: To describe the design of a randomized clinical trial to measure the efficacy of the iSupport-Brasil version on caregivers’ mental health and well-being. Methods: The participants will be randomized into Intervention Group (IG) (n=195) and Control Group (CG) (n=195). For three months, the IG will access the iSupport-Brasil platform, the CG will enter the electronic page of the Brazilian Alzheimer’s Association, and both groups will be emailed the preliminary version of the “Guia de cuidados para a pessoa idosa” e-book (a guide to providing care to the elderly) from the Ministry of Health. The data will be collected at three moments: baseline, and three and six months after the beginning of the intervention. Results: It is expected that it will be possible to provide diverse validity evidence about iSupport-Brasil as an online and free intervention alternative, as a preventive means and as a way to promote mental health among caregivers of people living with dementia. Conclusion: Through the evaluation protocol of this randomized clinical trial on the effects of the iSupport-Brasil program, it may become a reference for countries that plan to adapt and improve the iSupport program using digital health solutions.

RESUMO. Cuidadores informais de pessoas que vivem com demência tendem a sofrer problemas de saúde mental como resultado dos efeitos negativos associados às tarefas de cuidado. Assim, intervenções psicossociais para essa população são necessárias. O iSupport é um programa de apoio online para cuidadores criado pela Organização Mundial da Saúde. Objetivo: Descrever o desenho de um ensaio clínico randomizado para medir a eficácia da versão iSupport-Brasil na saúde mental e no bem-estar de cuidadores. Métodos: Os participantes serão randomizados em Grupo Intervenção (GI) (n=195) e Grupo Controle (GC) (n=195). Durante três meses, o GI acessará a plataforma iSupport-Brasil, o CG entrará na página eletrônica da Associação Brasileira de Alzheimer e ambos os grupos receberão por e-mail a versão preliminar do e-book Guia de cuidados para a pessoa idosa, do Ministério da Saúde. Os dados serão coletados em três momentos: linha de base, três e seis meses após o início da intervenção. Resultados: Espera-se que seja possível fornecer diversas evidências sobre os efeitos do iSupport-Brasil como alternativa de intervenção online e gratuita, de forma a promover a saúde mental entre os cuidadores de pessoas que vivem com demência. Conclusão: O protocolo de avaliação deste ensaio clínico randomizado sobre os efeitos do programa iSupport-Brasil pode se tornar uma referência para os países que planejam adaptar e melhorar esta intervenção, usando soluções digitais de saúde.

ABSTRACT Purpose To analyze the association between hearing loss and health vulnerability in children aged 25 to 36 months. Methods Analytical observational cross-sectional study conducted through child hearing screening in nine day-care centers. The screening consisted of anamnesis, otoscopy, tympanometry, transient otoacoustic emissions, and pure tone audiometry. For each exam performed, the 'pass' and 'fail' criteria were established. The children's residential addresses were georeferenced and a choropleth map of the spatial distribution was built, considering the Health Vulnerability Index (HVI). The analysis of the association between the HVI and the variables sex, auditory assessment, and region area of the household was performed using Pearson's Chi-square and Fisher's Exact tests. Results Ninety-five children of both sexes were evaluated, of which 44.7% presented alterations in at least one of the exams performed, being referred for otorhinolaryngological evaluation and subsequent auditory assessment. Of the observed changes, 36.9% occurred in the tympanometry and 7.8% in the transient otoacoustic emissions. Among children referred for reassessment, 9.7% were diagnosed with conductive hearing loss, 13.6% results within normal limits and 21.4% did not attend for assessment. Of the children who presented the final diagnosis of conductive hearing loss (9.7%), 1.9% were classified as low-risk HVI and 6.8% as medium-risk HVI. There was statistical significance between HVI and the child's place of residence. Conclusion The association between hearing loss and HIV was not statistically significant; however, it was possible to observe that 77.7% of the children with hearing loss resided in sectors with medium- risk HIV

RESUMO Objetivo Analisar a associação entre perda auditiva e a vulnerabilidade à saúde em crianças na faixa etária de 25 a 36 meses. Método Estudo observacional analítico do tipo transversal realizado por meio da triagem auditiva infantil em nove creches. A triagem constou de anamnese, meatoscopia, timpanometria, emissões otoacústicas transientes e audiometria tonal limiar. Para cada exame realizado foi estabelecido o critério de “passa” e “falha”. Os endereços residenciais das crianças foram georreferenciados e foi construído mapa coroplético da distribuição espacial, considerando o Índice de Vulnerabilidade à Saúde (IVS). Foi realizada análise de associação entre o IVS com as variáveis sexo, exames audiológicos e regional de domicílio por meio dos testes Qui-quadrado de Pearson, e Exato de Fisher. Resultados Foram avaliadas 95 crianças de ambos os sexos, destas, 44,7% apresentaram alteração em pelo menos um dos exames realizados, sendo encaminhadas para avaliação otorrinolaringológica e auditiva. Das alterações observadas 36,9% ocorreram na timpanometria e 7,8% nas emissões otoacústicas transientes. Dentre crianças encaminhadas para avaliação, 9,7% apresentaram diagnóstico de perda auditiva do tipo condutiva, 13,6% resultados dentro da normalidade e 21,4% não compareceram para reavaliação. Das crianças que apresentaram o diagnóstico final de perda auditiva do tipo condutiva (9,7%), 1,9% foi classificado como IVS de risco baixo e 6,8% como IVS de risco médio. Houve significância estatística entre IVS e o local de residência da criança. Conclusão Não houve associação com significância estatística entre alteração auditiva e IVS, entretanto foi possível observar que 77,7% das crianças com diagnóstico de perda auditiva residiam em setores censitários de risco médio do IVS.

Abstract The Pyroligneous extract is a product from the combustion of plant biomass with applications in the fields of health, industrial chemistry, and agriculture. The discovery of new molecules with therapeutic potential and of natural origin continues to be one of the great challenges for research centres around the world. The following work aims to analyze, through a technological prospection, the use of pyroligneous extracts for therapeutic purposes. To carry out the study, searches were carried out in documents deposited in Brazil, Europe, and the United States and searched on platforms specialized in patents. The number of inventions using pyroligneous extract with therapeutic applications is still quite small, however, innovations have been observed for the treatment of diseases of great clinical relevance such as cancer and hypertension. The systematic mapping of innovations is of great importance for the development of new technologies. health chemistry agriculture world analyze prospection purposes study Brazil Europe patents small however hypertension technologies

RESUMO A epidemiologia baseada em esgotos é uma importante ferramenta de saúde pública com grande aplicabilidade no enfrentamento à pandemia de COVID-19, visto que indivíduos infectados são capazes de excretar partículas de SARS-CoV-2. Diante desse contexto, este estudo objetivou correlacionar o número de casos de COVID-19 com variáveis físicas e químicas e presença do vírus em amostras de esgoto bruto provenientes de uma estação de tratamento de esgoto (ETE) do município de Lavras (MG) coletadas entre as 19ª e 25ª semanas epidemiológicas. As amostras foram concentradas pelo método de adsorção em membrana eletronegativa, e o RNA de SARS-CoV-2 foi extraído, detectado e quantificado por reação da transcriptase reversa seguida pela reação em cadeia da polimerase (RT-qPCR) utilizando-se oligonucleotídeos e sondas para o gene N. Ademais, as variáveis pH, sólidos suspensos totais e demanda química de oxigênio foram avaliadas. Os casos de COVID-19 foram obtidos de boletins epidemiológicos disponibilizados pela prefeitura. Na 24ª semana epidemiológica, observou-se redução na concentração viral (cópias L-1) concomitantemente às medidas de enfrentamento à pandemia iniciadas pelo município. Correlação positiva forte e significativa (p < 0,05) entre carga viral e número de casos confirmados foi obtida por meio do teste de Spearman, entretanto não houve correlação entre a presença do vírus e as características físicas e químicas do esgoto. Sugere-se, portanto, que novas pesquisas sejam realizadas com a finalidade de rastrear a concentração de SARS-CoV-2 em águas residuárias, corroborando, desse modo, com o enfrentamento à pandemia e a obtenção de sistemas de vigilância epidemiológica por meio do monitoramento de esgotos.

ABSTRACT Wastewater-based epidemiology is an important public health tool with great applicability when facing the COVID-19 pandemic, since infected individuals are able to excrete SARS-CoV-2 particles. In this context, this study aimed to correlate the number of cases of COVID-19 with physical and chemical variables and the presence of the virus in raw sewage samples from a sewage treatment plant (STP) in the municipality of Lavras, Minas Gerais, Brazil, collected between the 19th and 25th epidemiological weeks. The samples were concentrated by electronegative membrane adsorption method and SARS-CoV-2 RNA was extracted, detected, and quantified by RT-qPCR using oligonucleotides and probes for the N gene. Moreover, the variables pH, total suspended solids, and chemical oxygen demand were evaluated. COVID-19 cases were obtained from epidemiological bulletins made available by the municipal government. From the 24th epidemiological week on, a reduction in viral concentration (copies L-1) was observed concomitantly with the pandemic response countermeasures initiated by the municipality. A strong and significant positive correlation (p<0.05) between viral load and number of confirmed cases was obtained through Spearman’s test. However, there was no correlation between the presence of the virus and the physical and chemical characteristics of the sewage. Therefore, it is suggested that further research be carried out in order to track SARS-CoV-2 concentrations in wastewater, thus corroborating with the fight against the pandemic and the achievement of epidemiological surveillance systems based on sewage monitoring.

SUMMARY OBJECTIVE: This study aimed to suggest a care protocol for foreign-body ingestion, address the clinical aspects, and identify the ingested object, severity, and professional conduct. METHODS: This is a qualitative study. We used books and original articles published in national and international journals (BIREME, SCIELO, LILACS, and MEDLINE/PubMed) in Portuguese, Spanish, and English. RESULTS: The ingestion of a radiolucent object should be evaluated radiographically and with endoscopy for cases with symptoms of impaction and radiolucent objects. Coins are the most commonly involved foreign bodies. In asymptomatic patients, it often requires only a conservative form of management. Ingestion of batteries, magnets, and sharp objects carries a high risk of serious clinical complications and should have an endoscopic or surgical approach. In view of this, each pediatric emergency service, based on these recommendations, has the possibility to develop an individual protocol to identify and remove the ingested foreign body. CONCLUSIONS: Protocol of care for foreign-body ingestion in children depends on the object ingested, time of ingestion, symptoms, and local epidemiological context. This study provides some suggestions for decision-making in the conduct of health professionals.
